DeOxit is not cheap here either! We use it here mostly for scratchy pots, with the F5 formula having more lubricant compared to the D5 formula. They both remove corrosion and protect the contact surfaces without leaving an oily film, which is why I tried it on the variable caps of my FSL's too, to 'freshen' them. I use both formulas on my phasers to keep them running smooth. You don't need much so it lasts a long while......
